Grounded in ETSI EN 319 401 V3.1.1 and linked public sources. Use it as implementation guidance, not for legal interpretation. Use this page to decide what an assessor, customer, supervisory discussion, or internal audit should be able to inspect when a trust service provider claims that its ETSI EN 319 401 records are complete, protected, retained, and usable as evidence. ## What belongs in an ETSI EN 319 401 audit evidence pack? Start with clause 7.10 because it requires the TSP to record and keep accessible relevant information concerning data issued and received by the TSP, including after the TSP has ceased activities, for legal evidence and service continuity purposes. That makes the evidence pack broader than a folder of audit logs: it needs to show what was issued or received, how operation records were protected, and how records remain available for the stated retention period. Use the trust service practice statement, terms and conditions, information security policy, risk assessment, audit logs, incident records, backup tests, termination plan, legal-requirement evidence, and supplier register as the core index. Those artifacts are tied to separate EN 319 401 clauses, but together they explain whether the record set is complete, confidential, integrity-protected, and aligned with disclosed business practices. - Create a source-to-evidence index that names the relevant EN 319 401 clause, internal control owner, evidence location, retention period, and latest review date. - Include records of service operation, data issued and received by the TSP, significant environmental events, key-management events, and clock-synchronization events. - Show how current and archived records keep confidentiality and integrity, including the archive method and the controls that prevent easy deletion or destruction during the retention period. - Tie each retention period back to the TSP's terms and conditions, because clause 7.10 links service-record retention to the period notified under clause 6.2.

Organize it around the control areas that prove the TSP can operate and preserve evidence: risk assessment, published practices, terms and conditions, security policy, personnel and trusted roles, asset inventory, access and configuration control, incident management, continuity, termination, compliance, and supply chain. The pack should let a reviewer move from claim to proof without private context. For example, a claim that logs are reviewable should point to the logging control, a sample review record, the alerting or monitoring process, the person or trusted role responsible, and the retention rule that protects the log after the review. - Risk assessment: include management approval, residual-risk acceptance, chosen risk-treatment measures, and the review record required by clause 5. - Policies and practices: include the approved trust service practice statement, terms and conditions, information security policy, change-notice procedure, and evidence that relevant parties can access non-sensitive documentation. - Operations: include personnel training and trusted-role appointments, asset inventory and classification, access-control records, configuration reviews, vulnerability scans, and patch or exception documentation. - Incidents and continuity: include monitoring and audit-log reviews, incident response documentation, event classification, post-incident reviews, backup integrity checks, recovery-test results, crisis-management reviews, and continuity-plan ownership. - Suppliers: include supply-chain policy, supplier criteria, documented subcontracting or outsourcing agreements, service-level or audit mechanisms, supplier register, and planned supplier-review evidence.

EN 319 401 calls out confidentiality and integrity for current and archived service-operation records, complete and confidential archiving, availability of records for evidence of correct operation, and audit-log time synchronized with UTC at least once a day. Treat logs as evidence, not background telemetry. The pack should show which logs exist, why they matter to the trust service, how they are reviewed, how alerts are escalated, how deletion is prevented during the required period, and how records can be retrieved without exposing sensitive material unnecessarily. - List each record family: service-operation records, issued and received data records, audit logs, environmental events, key-management events, clock-synchronization events, incident records, backup records, and supplier records. - For each record family, capture owner, system of record, retention rule, confidentiality and integrity control, archive location, retrieval process, and destruction or long-term-transfer rule. - Evidence the daily UTC synchronization control for event time recording where audit logs are used to satisfy clause 7.10. - For incident logs, preserve the path from detection through documentation, reporting decision, containment, eradication, recovery, severity assessment, reclassification if needed, and post-incident review.

It focuses on traceability: every claim should have a clause, a record, a retention rule, an owner, and a way to verify that the evidence still represents the current trust service. Do not claim that EN 319 401 itself defines the independent assessment method. The standard states general policy requirements for TSP operation and management; it points readers to ETSI EN 319 403-1 for requirements about conformity assessment bodies assessing TSPs. - Version check: confirm the page and pack cite ETSI EN 319 401 V3.1.1 (2024-06) or deliberately document why a different version is in scope. - Scope check: name the trust service, locations, systems, trustworthy systems, suppliers, cloud services, and trust service components covered by the pack. - Completeness check: confirm that each clause-level evidence item has an owner, date, system of record, retention rule, and exception status. - Sensitivity check: separate assessor-shareable evidence from sensitive details that should be summarized, redacted, or inspected under controlled access. - Change check: trigger review when the practice statement, information security policy, trust service provision, systems, keys, suppliers, cloud services, or continuity assumptions materially change.

A clean narrative is not enough if records cannot be tied to the trust service boundary, disclosed practices, retention commitments, incident procedures, continuity assumptions, or supplier obligations. The safest approach is to remove broad claims that the available evidence cannot prove. Keep each claim narrow: what service it covers, what period it covers, which source requires or explains it, and which artifact shows the control actually operated. - Do not treat a generic information security policy as proof of clause 7.10 unless it maps to actual retained records and archive controls. - Do not list logs without showing review, alerting, retention, confidentiality, integrity, and deletion-resistance controls. - Do not leave retention periods implicit; clause 7.10 connects service-record retention to necessary legal evidence and the TSP's terms and conditions. - Do not omit termination evidence, because EN 319 401 requires continued maintenance or transfer of information needed to verify trust-service correctness when services cease. - Do not cite assessor expectations as EN 319 401 requirements unless the evidence pack distinguishes EN 319 401 from EN 319 403-1 or the actual assessment scheme.
